Abstract :
In this paper the theoretical investigation of giant tunnel magnetoresistance effect in the two-barrier magnetic tunnel junctions has been carried out. We assume that emitter and collector are ferromagnetic whereas two barriers and middle part of the two-barrier magnetic tunnel junctions consist of dielectrics. We use the two-band model of free electrons in ferromagnetic electrodes.
